Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.

Abstract: A stainless steel toilet resistant to corrosion by sea water. The toilet has a toilet bowl portion which is butt-welded to a rim. The welding is carried out while the inside surface of the weld line is flushed with argon gas. Similarly, a P-trap is butt-welded to an exit opening at the bottom of the bowl portion. A flush ring assembly is supported below the rim member. The result is a toilet which can be operated with sea water without corrosion for a period of years.

Abstract: An improved blow out toilet having remarkably low water volume usage. The toilet is of the type having a toilet bowl including a rinse ring having a rinse water nozzle directing water therein and a trap including a flush water nozzle. The improvement includes the reshaping of the toilet bowl and the reduction in size and reshaping of both the rinse water orifice and the flush water orifice.

Abstract: An improved sprayhead for group washfountains of the type having several washing stations positioned around a sprayhead located over a single bowl. The washfountain has a hollow sprayhead having an exterior wall which holds not only the nozzles but also a soap reservoir and hand actuated buttons. The valves which supply water to the nozzles are preferably positioned in the pedestal below the bowl of the washfountain.

Abstract: A push button assembly for moving a volume of fluid out of and into a port. The assembly has a housing containing a rubber-domed diaphragm. The domed diaphragm is designed so that it is deformable but readily returns to its original shape. The pressing of the push button depresses the diaphragm, thereby forcing air or other fluid out of the exit port. When the button is released, the diaphragm returns to its original shape pulling fluid back through the port.

Abstract: An improved needle valve having a protective cap. The valve is of the type having an adjustable needle valve held in a housing connected to an air line. The needle valve meters air flow into a line and the improved valve has a cap with slits in the side thereof. The cap is oriented so that the slits face downwardly and, thus, any water or debris falling on the valve is conducted away from the air inlet portion of the valve. The valve is mounted so that it may be rotated 360 degrees about its point of mounting.

Abstract: An improved, remote controlled valve and dual push button assembly, having a hand operated push button which, when depressed and released, opens a water valve for a predetermined length of time after which the valve closes. The valve is also connected to a foot operated push button which, when depressed, holds the valve in an open configuration as long as the foot button is depressed. The improved valve and button assembly provides an air flow path through the foot button when the foot button is not depressed. The air flow path utilizes a hole in a diaphragm of the foot button which communicates with an air flow path in the base of the piston which depresses the foot button diaphragm. The disclosure also includes a check valve held in the needle valve which is a part of the timing mechanism of the hand operated button. The check valve prevents the flow of air out through the needle valve and permits air to only flow in through the needle valve.
